【摘要】 目的探讨冠状动脉CT成像(CTA)在心肌桥-壁冠状动脉临床诊断中的价值。方法采用64层螺旋CT对327例患者行冠状动脉CTA检查,观察有无心肌桥,并对异常段壁冠状动脉进行狭窄评估。心肌桥病例均行冠状动脉造影检查并对比。结果 327例患者共发现57例66段心肌桥,其平均长度为(4.72±0.93)mm,平均厚度为(2.04±0.62)mm,壁冠状动脉的狭窄程度为(33±20)%。对比冠状动脉造影检查共发现29例35段心肌桥,两者差异有统计学意义(P<0.05)。结论冠状动脉CTA检查可以清晰显示心肌桥和壁冠状动脉,与传统造影方法相比对临床诊断有重要意义。更多还原

【Abstract】 Objective To discuss the clinical value of CT angiography(CTA) in diagnosis of myocardial bridge and mural coronary artery.Methods Three hundred twenty-seven patients were performed 64 slices CT angiography to observe myocardial bridge,and evaluate the stenosis of mural coronary artery.All cases with myocardial bridge received coronary arteriongraphy and comparison.Results Fifty-seven cases with 66 myocardial bridge segments were found,with mean length(4.72±0.93) mm,mean thickness(2.04±0.62) mm,the mean stenosis of mural coronary artery was(33±20)%.Twenty-nine cases with 35 myocardial bridge segments were found by coronary arteriongraphy,the difference between them has statistical significance(P<0.05).Conclusion CTA can clearly show myocardial bridge and mural coronary artery,and it has important significance in clinical diagnosis compared with traditional coronary arteriongraphy.更多还原
